Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.

Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

Even though we were delayed, we were able to make our connection

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

The internet service I paid for didn’t work at all and the flight crew was not very friendly.

The planes are so dirty! Food crumbs and finger print smudges, Dust over the vents and carpet stains. It’s disgusting.

Overall it was good. The flight was bumpy at times, but the pilot made us aware every time. As a result, no snacks/drinks were made available. Seats were tight but that’s okay as I had a window seat.

Both of the first class flight attendants were rude, to everyone, not just us. The one in coach was more helpful to us than the ones in first class!

Air condition was not working for long both after boarding and also after landing ; unbearably hot and suffocating

It was canceled at the last minute. While I was literally at the airport. Messed my entire trip up.

Flight was on-time, boarding was flawless and the crew was friendly.

Not to have gotten delayed by 2+ hours for the fourth straight American flight. They're the worst.

Did not get any refreshments. Crew was very nice but limited. Small seats

Wish a flight with more than 2 hours with some snack rather than just cookie/biscuit.

I didn’t like anything, being platinum pro get you absolutely nowhere and does not increase the customer service treatment whatsoever anymore. My flight was canceled and they put me on a flight eight hours later that would’ve got me back in the middle of the night. They could’ve easily move me up to an hour Prior on an earlier flight. My second flight was unreasonable to take, the third flight was also canceled due to mechanical issues like the first flight. I don’t know what’s going on with American, but they are falling apart, after seven flight changes I finally got home, Unreasonable.

This was a horrible American Airlines experience, and it discourages me from flying with them again. It may have stemmed from a mechanical delay, but it appeared that the team was unprepared to respond to the delay. After boarding, we waited an hour before finally taking off. After landing at our destination, we waited an additional hour on the tarmac waiting for a gate (at 8:00pm) to be assigned and cleared. The flight crew did their best, but they were clearly tired and also ready to be done for the day. Because of the delay, I missed a connecting flight. It was a very poor experience.

Fantastic! If it had not been for a check-in agent in Knoxville I may have not gotten my passes on British Airways. I couldn’t check-in online because British Airways had messed us the info on my tickets to London & Inverness. AA’s was great! British Airways was a continuous series of delays and frustrations.

Wheelchair was waiting for me,changed to a better seat which was great as it's hard for me to walk

Not great!!! Seats in Business class were horrible; no cushion!!!

No entertainment since it was a 3 hr flight. Good leg room for economy.

Flight from Washington to Munich it was disappointing. I do not get the seat for what i pay. And the crew were rude with people which speaks other languages than german!

Gate was difficult to know. Flight number from Lufthansa directed to a different flight number by SunXpress, which was different from my actual flight per the airport. Multiple people (at least 3 others) were lost with me at the airport in Munich (I didn't know them) trying to get to a different terminal. Too many confusing signs, and no one could help. When I found some Staff members (surprisingly difficult) told me "you have to figure it out." Yeah, that's why I'm asking and walking around in circles. Thought I would miss my flight, turns out I had plenty of time, but I couldn't figure it out for the first hour. 90% airport's fault, not SunExpress.

Getting boarding pass for international connected flight was a hassle. Huge libe to get boarding pass after two connected international flight is excessive to put someone on stress. They should provide online checking for all flights

The most horrific experience we had with the airline that we had in our life Everything was substandard at best. For just one hot tea they charged 4 euros We paid for Lufthansa months in advance ,to get there they didn’t have us in record and after 4 and a half hours layover we almost we got one seat at the first row and one in the back of the plane On top of that our suitcase was seriously damaged and it’s unusable. Here we are halfway around the world in foreign language having to fix this on our vacation time Would you kindly and quickly resolve this matter

That was no easy way to get on board in the plane was very hot and I couldn’t talk to the crewmember there super rude and they couldn’t fix the AC. They felt very uncomfortable for 3 1/2 hours flight. I would not use airline next time. Thank you.

Unable to get Lufthanza code to obtain a boarding pass for my flight. Had to exit and re-register to get on the flight. Extremely frustrating.

My flight was delayed for more than an hour due to planning amd scheduling issues all of which were Lufthansa's responsibility. They failed dismally at doing what was agreed upon and their reparations were inadequate and completely useless to us. The flight crew were lovely however the ground crew working out of their customer service were the modt rude and obnoxious people i have ever had the misfortune of meeting.

The crew that checked at the gate was completely unprofessional, i had a child, stroller and a carry on luggage and the crew did not bother providing any help getting down 3 flight if stairs. I asked for hel and they ignored me

Seat pitch is not enough to eat comfortably. When seat in front is reclined, your screen comes closer to your face. Ryanair seats are actually more comfortable.

The crew were professional and friendly. It was the most uncomfortable international flight I've ever flown. Crammed in passengers. No overhead space to put my bag. No leg room and unable to recline seat due to seats too close together so it upset passenger behind me! Upgrade price to get 2 inches of more space unreasonable.

Business class to Istanbul. Packed flight. Cabin crew seemed incapable of differentiating between economy and business passengers with regard to access to the WC which meant whole flight I had people standing in aisle and leaning into my aisle seat, queueing for the front WC. Crew put it down to a lack of curtain between the two classes. The seats, for a 3hrs55 min flight were just standard seats with middle seat unoccupied. So nothing special apart from the food, which was mediocre. Aside from the roast chicken dinner (‘special’ traditional British menu option, which looked poor but tasted good I gather). However 2 king prawns does not make a main course salad.

Pilots seemed fine but one stewardess seemed crabby, but it was tolerable just didn't seem to be projecting a service attitude. I understand we all have those days. Return flight on 8/8/24 noticeable better / normal.

Terrible. Missed my flight to final destination because of delayed British Airways flight. Had to spend 12 hours in airport and $1500 for new plane tickets

It said that there was wifi. During the flight there was no wifi and while waiting at the gate the phone services already got cut off so I wasn’t able to say I am taxiing from the gate to my husband. This left me with an uncomfortable feeling. So I was waiting on the WiFi connection during flight and that never happened.

I asked for a wheelchair. I have a back health condition. I had to walk a lot

Boarding = No one respected the boarding groups. The ground crew did nothing to enforce the boarding system. What is the point of being a Gold member when there are no benefits to that? Tired old plane

The flight and the staff was excellent. Only bad thing is no entertainment and you have to pay for anything other than water.

Flight departed 45 mins late Crew great Food items missing from breakfast
